UNITED STATES PATENT OFFICE CHAIR Csar Victorino J annello, BuenosAires, Argentina Application January 28, 1947, Serial No. 724,750

3 Claims.

My present invention refers to a novel chair structure.

One object of my present invention is to provide a simple elastic andresistant support structure for chairs which is of relatively low costand easy to manufacture and which consists of a single bar of round ironbent in such a manner as to :provide the legs of the chair, the rests ofthe chair seat, and means for mounting the back-rest of the chair.

Another object of my invention is to provide a chair structure,comprising a seat, a support consisting of a single bar of round iron,and a back-rest mounted on the free ends of said bar, the arrangement ofthese parts being such that only a few cramps are necessary forassembling the chair.

Still another object of my invention is to provide a chair structure,comprising a seat of wood or any other suitable material, a support forsaid seat consisting of a single bar of round iron simply bent in zigzagso as to provide a number of bottom knees for supporting the chair and anumber of upper knees for carrying said seat, and a back-rest providedwith a pair of guide grooves and a pair of diverging channels forreceiving the free ends of said bar and for thus mounting said back-reston said free ends of this bar.

My invention further consists in the details of construction andarrangement of parts as will be fully described hereinafter andparticularly set forth in the appended claims.

The invention will be more readily understood by reference to theaccompanying drawing forming a part of this specification and in whichFigure 1 is a perspective view of the chair structure according to myinvention,

Figure 2 is a detail view showing in sectional elevation the back-restof the chair structure of Fig. 1.

With reference to the accompanying drawing,

, a chair seat I of wood or any other suitable material is carried by asupport 2 which according to my invention is made of a single elongatedmember, such as a bar of round iron.

The round iron bar 2 is simply bent seven times in zigzag as shown so asto form four legs 3 and three rests 4 for the seat l suitably fixed inplace onsaid rests as by cramps 5 or the like.

The free ends of the round iron bar 2 extend upwards and areinterconnected by means of a back-rest 6 which for this purposecomprises a cut-out portion 1 provided at the side edges thereof withgrooves 8 which at their upper ends communicate with diverging channels9 cut into grooves 8 are of sufiicient Width to receive and retain theupper portions of the bar 2 immediately below the bent ends 2 thereof,so that the back-rest remains fixedly secured to the free ends of thebar 2.

Due to the nature of this bar of round iron 2 and of the supportstructure as described, the chair has sufiicient elasticity to secure acomfortable seating.

What I claim as new and desire to secure by Letters Patent is:

1. A chair comprising a seat, a back-rest, a single elongated memberbent in zig-zag fashion providing four legs for supporting the chair andthree rests for supporting said seat, and means securing said seat tosaid rests, said back-rest having a pair of spaced diverging channels,the free ends of said member extending upwards and outwardly above saidseat and being disposed within said channels whereby said back-rest ismaintained in fixed relation thereto.

2. A chair comprising a seat, a back-rest, a single elongated memberhaving a :plurality of bends arranged in zig-zag fashion, therebyproviding a plurality of legs for supporting the chair and a pluralityof rests for supporting said seat, and means for securing said seat tosaid rests, said back-rest comprising a cut-out portion, guide groovescut into the side edges of said cut-out portion and a pair of divergingchannels communicating with said grooves at the upper ends of thelatter, said grooves and said channels receiving the free ends of saidmember for mounting the back-rest on said free ends.

3. A chair comprising a seat, a back-rest, a single elongated memberhaving a plurality of bends arranged in zig-zag fashion, therebyproviding a plurality of legs for supporting the chair and a :pluralityof rests for supporting said seat, and means securing said seat to saidrests, said back-rest having a pair of spaced diverging channels, thefree ends of said member extending upwards and outwardly above said seatand being disposed within said channels whereby said backrest ismaintained in fixed relation thereto.
